Adding a custom constant sum box to an image

Question

Hi, 
My collaborators and I are trying to create a question that looks like this:
Our code works for the most part, but we can't seem to get the "total" box to display the sum of all other 5 boxes. 
Here is the code:

function findTotal() {

// Put all 'qty' items in array named 'arr'
  var arr = document.getElementsByName('qty');

// Starting value == 0
  var tot=0;

for (var i=0; i

Try putting your findTotal() function (without the script tag) inside the Qualtrics.SurveyEngine.addOnload() function.
